coca cola	1 leader	family dollar	1.50
beker	2	mr.groves	0

Detailed Procedure

Results

My results are that coke-cola is the best soulition to tarnish coins because there is a certian cemmical called
Merchandise 7X. mtn dew was the seconded because the sugger is so strong that it makes the bubles got to the top.Mtn dew has less sugar that coca-cola. everytime you take a sip all the sugar rises from the bottom.

Conclusion

My conclusion is that coca-cola is the best soulution to tarnish coins. I did only one test but it was obvious which soda would tarnish both coins.There is a cemical thats in coca-cola that Makes the soda rare.Mtn dew came in seconded because the third drink was water. I Knew that coca-cola was the one that was going to tarnish more. did you know that coca-cola can desolve a engine in less then a mounth. I took notes while i was doing the exsperament. the whole point of this project was that it proves that soda could be most effective then regular drinks.

Discussion

I observed what coca-cola can do when you use It.It has many sugars and calories in it which causes the coins to dissapear. I had to study how you can tarnish a coin but It didint say coca-cola so I wanted to prove that this substance could tarnish a coin infact any coin. When you take a sip of coca-cola all of the sugars come up and makes to burp and sometimes hurt your nose. Maybe If I show people what soda can do then they might try a bevrage low fat. One of the keys to obestiy is soda and junk food.

Nickel and Copper are often found together because nickel and copperhave the same densities so when they are layered together between other minerals.The copper with 25% nickel with 0.05-0.4% manganese is commonly used for the manufacture of coins, medals and other semi valuable applications.

Abstract

After my project i concluded that coca-cola is one of the soda,s thats bad for you in the top chart.well i wonna prove that soda is
bads for kids and it can cause diabeties.my graph of hypothisis came true and my data was simular to my hypothis. my procedure was accurate and my independent and my dependent variable took a little reasearch but not much.my science teacher gave an example for every step so i took all of my research and put in my conclustion and i think my conclustion is very specific.when i did my project i relized before i put the coins in the coca-cola it was shinny but when i took it out it was tarnished but in a wired way like it was even more shinny.i didint have alot of background research because i was more focus on the exsperiment.after my exsperment i relized that how much compinies put so much stuff in soda that you dont relize what your drinking.
